College Point residents fear a developer and state regulators aren’t doing enough to clean up underground poisons from a former dump where 86 new homes are to be built.

The landfill in Queens harbors everything from cancer-causing PCBs to metals and petroleum products in its soil, according to an environmental-impact statement submitted by College Point Properties. The company, a subsidiary of Los Angeles real estate firm Oaktree Capital Management, wants to build on the 81/2-acre site.

Illegal dumping in the 1960s and 1970s transformed the wetland into a graveyard of burned-out cars, crushed tombstones, discarded batteries and oil drums. The decomposing metal is causing the build-up of toxins, according to state officials.

Although the developer submitted a remediation plan to clean the site, local residents don’t think it’s enough.

“The area is full of dangerous toxins at high levels,” said marine biologist and Pace University professor James Cervino, who lives down the street from the site and has conducted tests there.

“My goal is to get it cleaned up to the level it should be to make it safe, and I don’t believe their current plan does that.”

The developers’ plan, which was approved by the state Department of Environmental Conservation over the summer, calls for the removal of oil three feet under the surface, as well as chemical hot spots.

The DEC said it would monitor the cleanup with the state Department of Health so that it will be “fully protective of public health and the environment.”

But Cervino and other community activists are anxious.

“There are toxins as far as 18 feet under the surface,” Cervino said. “Those toxins are seeping into the underground aquifer and spilling into the wetlands. How is cleaning three feet going to fix that?”
